i This invention relates to any improved apparatus for the preservationof foods or the like, and for the cooling of air within a room, byrefrigeration.

The primary object of the invention is to Iprovide av simple andefficient apparatus of the above kind embodying an automaticrefrigerator having a refrigerating chamber provided with a warm airinlet, a storage chamber for foods or the like, a casing for the storagechamber spaced from the latter to permit circulation of cold air aboutthe same, anda refrigerating'unit having anevaporator arranged withinthev refrigerating chamber, the refrigerating chamber communieating withthe space about the storage chamber to supply cold air to said space,said casing having a cold air outlet, anda cooling radiator located inthe room and 'having an air inlet communicating with the cold air outletof the storage chamber casing and an air outlet communicating with thewarm air inlet of the` refrigerating chamber.

A more specic objectv is to provide an apparatus of the above kind inwhich the ,automatic refrigerator is arranged in the upper portion of abuilding and the radiator is located on v a lower floor oi' thebuilding, in combinationwith a vertical Ilue in the building with whichthe air outlet oi' thelstorage chamber and the air inlet and the airoutlet of the radiator communicate, a second refrigerator on said lower-iloor having a storage chamber provided with an air inlet and van airoutlet communicating with said flue, and

dampers in said flue for varying the amount of cold air diverted fromsaid ilue through the second refrigerator and the radiator.

Another object is to provide an' apparatus of the above kind embodying aportable refrigerator and air conditioning cabinet hafving a compartmentfor the radiator whifhl isprovided with a fora'minous walland acompartment divided into the refrigerating and storage chambers. Other/and more specific obj cts and features of the invention will become aparent from theffollowing description, when considered in connectionwith Athe accompanying drawings.

Referring to the embodimentshown in Figs. l to 3 inclusive, 5, 6, 'I and8 respectively vindicate fthe basement and the first, second, and thirdilors of a building having a vertical flue or conduit 9 that extendsfrom the upper iloor 8 to the basement 5 and communicates at its lowerend with a horizontal conduit or passage I0 beneath the basement floorII. p y

Located in the upper floor 8 is an automatic refrigerator'R having arefrigerating chamber I2 provided with a warm air inlet I3 that isadapted to be connected in any suitable manner to the passage I0. l Therefrigerator shown has angautomatic yelectrically operated refrigeratingunit U suchr as is commonly employed in electric household refrigeratorsand which includes an evaporator I4 located in the chamber I2. Therefrigerator R alsohasan encased storage chamber I5 for foods or thelike about which is-a space for the circulation of cold air from thechamber |2.- The casing of chamber I5 has a cold air outlet I l whichcommunicates with the upper end of ilue 9.

Located on the floors 6 and l are secondary refrigerators RI and-R2,each having a storage lspa'ce I8 provided with an air inlet I9 and a'nair Also located onthe doors-f6 and 'I are-cooling radiators 2| a'nd 2Iaeach having an air inlet 22 4and an air outlet 23 communicating with theue 9. Pampers 24 are provided in the flue 9 for varying the amount ofcold air diverted from flue 9 through the refrigerators RI and R2, andother dampers 25 are provided in flue .9 for varying the amount of coldair diverted from said flue through the radiators 2|. While valves maybe used tov close the inlets 22 of the radiators in cold weather, theyyhave not been shown because of their elementary nature. 1

The apparatus above described provides acentral refrigerating plant foruse on the upper door and for supplying cold air to the coolingradiators and refrigerators on lower floors. In order to prevent passageof odors to the radiators RI and R2, deodorizing air filters 26 areplaced inthe air refrigerators RI and R2 and in the flue 9 to circulatethe air through the apparatus.l

In operation, air enters the chamber I2 through inlet I3 and isrefrigerated by theunit U. This cold air passes around chamber I5 andinto flue 9, and then circulates through the `refrigerators Rl and R2and radiators 2i and 21g so as to preserve the articles in the chambers.4land cool the air on the floors 6 and 1. `Thriftemperature of thewarmed air delivered to pass `ge lll. is lowered within the latter dueto therein, condition of the ground about said passage., his reduces thecooling required of unit U whe turns to chamber I2 fromk the passtpurpose oi' dampers 24 and 25 has been explained, and it will be seenthat this embodiment provides a normally closed air circuit in` whichrefrigerators and radiators for apartments on separate floors cfabuilding are serviced by a refrigerator in an apartment on a higherfloor..

Referring to Fig. 4, thereis shown aportable refrigerator and airconditioning cabinetfjp provided with a lower compartment 28- h'alving acooling radiator 2lb therein and also provided with a loraminous frontwall 29. The cabinet also has an upper compartment divided lnto a refrigerating chamber l2a and a spaceJcGa having storage shelves I5alocatedtherein so that cold air may circulate about said storage sheliles from the chamber I2c. The space IGa communicates with the inlet 12aof radiator 2 Ib, and the'outlet 23d of radiator 2lb communicates withthe'chamf ber 12a via the upper portion of space'. ISa. The" cabinet hasan automatic refrigerating unit Ul including an evaporator Ila locatedin the chamber 12o.

The space |60. may contain a watertank 4or fountain 30 to hold water fordrinking purposes, and a watcrtank 3| may be mounted in one end of thecabinet and provided with an open top registered with an opening 32 inthe top of the cabinet so as to provide for humidifying the air in theroom, inwhich the cabinet is used. Thermo-typhlon or forced circulationmay be used to this embodiment. i

In oderatiom air circulates from chamber I2a through space Ilia andradiator 2lb, back to the chamber l2a via outlet`23a and the top ofspace Ifia. Articles on the shelves |5a and the water in tank orfountain30 will thus be cooled, and air entering and leaving the compartment 28will becooled by the radiator 2lb.

`From the foregoing description, it is believed that the constructionand operation; as wel] as theL advantages of the invention, will bereadily understood and appreciated by thosev skilled in the art. f i
